Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF8

From the JVM™ Tool Interface documentation…
Since the command-line cannot always be accessed or modified, for example in embedded VMs or simply VMs launched deep within scripts, a  JAVA_TOOL_OPTIONS  variable is provided so that agents may be launched in these cases.
By setting the (Windows) environment variable  JAVA_TOOL_OPTIONS  to  -Dfile.encoding=UTF8 , the (Java)  System  property will be set automatically every time a JVM is started. You will know that the parameter has been picked up because the following message will be posted to  System.err : Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF8
